Installments are fetched from the external installment service using the card BIN and the current basket amount, then filtered by the active installment filter rules. **Preconditions**: * Basket must not be empty * Payment option must be of Masterpass REST type **Page Context**: * `installments`: List of installment options returned by the remote installment service. Each entry contains `id`, `label`, `bin_number`, `installment_count`, `interest_rate`, `interest_amount`, `final_price_with_interest`, `monthly_price_with_interest`, and `is_active`. * `installment_messages`: List of informational strings returned by the installment filter service. **Step Completion**: This page is considered already completed when both of the following are true: * The remote installment selection has been saved, **and** * The selected payment option is of Masterpass REST type. **available\_for\_post\_order**: `true` ```json {"openapi":"3.1.0","info":{"title":"Overview","version":"1.0.0"},"tags":[{"name":"Masterpass Payment","description":"# Checkout Masterpass Payment\n\nIntegrate the Masterpass digital wallet into your checkout.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://apidocs.akinon.com/commerce-openapis/checkout/masterpass-payment/get-masterpass-remote-installment-selection-page-context.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
